• Thus, the Hox genes are a subset of homeotic genes.
• Observations of homeotic mutations led to the formulation of the E . Meyerowitz.
• An example of a homeotic mutation is the so-called Antennapedia mutation.
• Homeotic mutations work by changing segment identity during development.
• The homeotic genes are activated by gap genes and pair-rule genes.
• Homeotic genes and Hox genes are described briefly.
• De
  鹡itive evidence for a genetic basis of some homeotic transformations was obtained by isolating homeotic mutants.
• De
  鹡itive evidence for a genetic basis of some homeotic transformations was obtained by isolating homeotic mutants.
• A key early discovery was of homeotic genes that regulate development in a wide range of eukaryotes.
• Some MADS-box genes of flowering plants have homeotic functions like the HOX genes of animals.
• Mutations in some homeotic genes can often be lethal and the cycle of life will end at embryogenesis.
• The
  鹯st homeotic mutant was found by Calvin Bridges in Thomas Hunt Morgan's laboratory in 1915.
• Most of the Hox genes in mammals show an expression pattern that parallels the homeotic genes in flies.
• The bithorax group of homeotic selector genes control the specializations of the third thoracic segment and the abdominal segments.
• Later during development, homeotic genes are expressed in the nervous system in a similar anterior / posterior pattern.
• MCB WikiProject rates Homeotic selector gene a Stub on the quality scale, and Low on the importance scale.
• Somites have unique positional values along this axis and it is thought that these are specified by the Hox homeotic genes.
• Manatees are unusual amongst mammals in possessing just six cervical vertebrae, which may be due to mutations in the homeotic genes.
• These types of mutations, where one organ in a developing organism is replaced with another, are known as homeotic mutations.
• Homologs of the Homeotic selector gene are found in a variety of species, varying from cnidarians to nematodes, to mammals.
